XOLARIS: A 24-Month, Prospective, Natural History Study of 201 Participants with -Associated X-Linked Retinitis Pigmentosa.

Objective: To improve the understanding of the natural disease progression of ()associated X-linked retinitis pigmentosa (XLRP).

Design: A multicenter, prospective, observational natural history study over 24 months.

Participants: Male participants aged ≥7 years with a pathogenic variant in the gene, a best-corrected visual acuity (BCVA) score of ≥34 ETDRS letters, and a mean 68-loci retinal sensitivity (assessed by microperimetry) of 0.

Subretinal timrepigene emparvovec in adult men with choroideremia: a randomized phase 3 trial.

Choroideremia is a rare, X-linked retinal degeneration resulting in progressive vision loss. A randomized, masked, phase 3 clinical trial evaluated the safety and efficacy over 12 months of follow-up in adult males with choroideremia randomized to receive a high-dose (1.0 × 10 vector genomes (vg); n = 69) or low-dose (1.

Cone structure in patients with usher syndrome type III and mutations in the Clarin 1 gene.

Objective: To study macular structure and function in patients with Usher syndrome type III (USH3) caused by mutations in the Clarin 1 gene (CLRN1).

Methods: High-resolution macular images were obtained by adaptive optics scanning laser ophthalmoscopy and spectral domain optical coherence tomography in 3 patients with USH3 and were compared with those of age-similar control subjects. Vision function measures included best-corrected visual acuity, kinetic and static perimetry, and full-field electroretinography.
